The energy balance also suggested that bioremediation and soil washing are more sustainable technologies as a lower required energy (i.e. 16 and 14&nbsp;kWh&nbsp;m-3, respectively) than LTTD (i.e. https://www.selleckchem.com/products/ci994-tacedinaline.html 417&nbsp;kWh&nbsp;m-3) is needed.This study deals with the preparation of activated carbon (AC) from poly(ethylene terephthalate) (PET) waste and with the physicochemical characterization of AC and its use as adsorbent of bisphenol A (BPA) in aqueous solution. AC was prepared by chemical activation with KOH and by physical activation in steam. The activation with KOH was carried out by impregnation first of PET by wet and dry routes at the PET/KOH weight ratios of 11, 13, and 15 and by carbonization then of the resulting products at 850&nbsp;°C for 2&nbsp;h in N2 atmosphere. The activation in steam was performed by heating at 900&nbsp;°C for 1&nbsp;h. The ACs were characterized by N2 adsorption at -?196&nbsp;°C, mercury porosity, mercury density measurements, FT-IR spectroscopy, and measurement of pH of the point of zero charge (pHpzc). The activation yield is 58.4-49.4% with KOH in aqueous solution, 75.8-23.9% with solid KOH, and 5.9% with steam. Using solid KOH, greater developments of a more heterogeneous porosity with increasing impregnation PET/KOH ratio are achieved. For SK15, SBET is 1990&nbsp;m2&nbsp;g-1 and the pore volumes are 0.71&nbsp;cm3&nbsp;g-1, micropores; 0.81&nbsp;cm3&nbsp;g-1, mesopores; and 1.77&nbsp;cm3&nbsp;g-1, macropores. The data of BPA adsorption fit better to the Ho and Mckay second order kinetic model than to the Lagergren first-order kinetic model and to the Langmuir equation than to the Freundlich equation. From the kinetic and thermodynamic standpoints, the adsorption process of BPA is more favorable for SK15.This study explores the determinants of intention and behavior towards environmentally friendly agricultural (EFA) food in China. We conduct the influencing factor model on behavioral intention and behavior toward EFA food by extending TPB model with the theory of public environmental policy and perceived value and trust. The empirical analysis revealed that public environmental policy and subjective norm positively affect behavioral intention and behavior for purchasing EFA food. However, trust and attitude have no significant effect on the intention of purchasing EFA food. Subjective norm and perceived behavioral control have a significant effect on intentions toward purchasing EFA food. And the effect of intentions on behavior towards purchasing environmentally friendly agricultural food is significant and positive. Moreover, we have found that female consumers may consume more of environmentally friendly agricultural food compared with males, and the consumption of EFA food was significantly different across different level of income.Optimal stockpiling is the best possible strategy to overcome the problem of peak oil periods of oil producer economies. We measured the properties of strategic petroleum oil reserve and general equilibrium and its peak oil effects. Measured the optimized scales of SPR through using oil price model, global oil market, and depletion effects of oil production classification. The peak oil period occurs from the interection between the geological era, proficiency in a practical skill, economy of consumers, and geopolitics, and the quality of deciding of demand and supply in which we have done a general dynamic balance model. Results reveal that peak oil time periods may lead towards diverse oil prices time profiles, economic development, and commodity flows. Interestingly, the macroeconomic effects of peak oil and the trajectories in objective function of two options maximize the households' welfare and oil revenues and its effect on growth trajectories of oil-consuming countries. If an oil supply disruption happens, the rate of oil acquisition will be considerably decreased, though it may not be a good strategy to interrupt the activities of oil reserve with the aim of minimizing the overall costs.This study aims to synthesize a dust suppressant for controlling coal dust pollution in open yards using natural polymers. Guided by graft copolymerization theory, potassium persulfate acts as an initiator to excite the free radicals of collagen and sodium alginate, allowing them to combine with acrylic acid and acrylamide to form a new polymer. The TG curve indicates that the thermal stability of the polymer is superior to that of the raw material. Scanning electron microscope (SEM) images show that the product can reduce the generation of dust by bonding the pulverized coal. With CCD method, when the monomer concentration increases in a certain range, the cohesive ability of the product to coal increases first and then decreases. Initiators and crosslinkers showed the same pattern. A series of performance experiments show that the product has a dust suppression rate of 98.7% at a wind speed of 14&nbsp;m/s, and maintain one of 94.5% at a wind speed of 8&nbsp;m/s after a rainstorm. In addition, there was no significant loss in dust suppression performance and compressive strength of the solidified layer after wind and rain. Sunlight, low temperature, and high temperature have little influence on the dust suppression effect of the product, which indicates that the product has better weather resistance and helps to suppress dust for a longer time in open air conditions.This paper analyzes the extent to which CEO (chief executive officer) tenure affects the corporate social and environmental performance of all nonfinancial Chinese firms listed in Shanghai and Shenzhen stock exchanges during 2009-2015. The study uses a fixed-effect panel regression model by considering the overtime data across the firms. 2SLS regression model then is used to control the problem of endogeneity. The study confirms the negative effect (8.8%) of the increase in CEO tenure on the corporate social and environmental performance. The findings also explain that the corporate social and environmental performance of CEOs increases significantly in the initial years of service than in their later years. The study concludes that an inverse relationship between CEO tenure and corporate social and environmental performance is more pronounced with a higher percentage of independent directors, where CEOs have longer anticipated employment tenure and firms under state control, consistent with the signalling explanation of career concern and career horizon effect.
